To all whom it may concern: 1

Be it known that I, ALEXANDER McKm- BIN, a citizen of theUnitedStates,and a resident of the city of Chicago, m the county of Cook and State ofIllinois, have invented Y certain new and useful Improvements in fluidtherethrough.

IValves; and

It is an object of my invention to provide a valve which is simple inconstruction and has improved means for controlling the flow of fluidtherethroligh.

. stem to avoid leakage, wherein the and a valve Another object of myinvention is to provide a valve having a disk movable relativelythereto, and a packlng disk likewise perforated and held betweentheplate .and valvedisk under pressure to'maintain a fluid tight joint. 7

Another object of m invention is to provide improved means or packingthe valve packing means is adjustable without straining the of Fig. 4.

' specification and valve,

' My invention also has other important objects which will appear fromthe following the accompanyin drawings, in which I have described allshown my inventionin a preferred form.

which form an internal diameter somewhat perforated plate- Fig. is aninside view of the cup-shaped cap WhlCll closes the-bottom of. the valvecasmg.

As shown on the drawings:

The reference numeral 1 indicates the valve casing, which has a pair ofoutlet branch openings 2, and an opening 31 at one side of the casingintermediate of the branch 1 openings, which latter opening issurrounded by a flange 3, and has a shallow annular seat or recess 4, atthe inner edge of the flange. A partition or plate 5, which maybe madeintegral with the casing 1, or otherwlse as des1red,'is located in theopening 31,

and has the outersurface thereof flush with the base of the seat orgroove4, and this plate centrally perforated and also has a pair ofdiametrically'opposite openings 6 which are adapted to afforda-passageway for the .fluid into the interior of the valve casing 1.. Acup-shaped cap 7, which has greaterthan the diameter of the opening 31,is attached to the casing 1 and'has a threaded inlet openmg 8, thereto,to which the inlet pipe is connected, also has a flange 9, whereby theca s secured to the flange 3 ofthe casing 1, ymeans of the bolts 10. iThe groove 4, is of substantially the same diameter asv the interior ofthe cap 7 andhas a disk 11, of packing material seated thereinpandheldso as to remain stationary, and thls d1sk has a central perforationmatching the central perforation of the part1t1on 5, and also has openin32, therethrough, which match the openmgs 6, of the plate 5. A valvedisk 12, of a proximately the same diameter as the dis 11, is heldthereagainst andhas a hub 13, which extends through the central;perforations ofthe packing d1sk'11 and artition 5, and has asquaresocket in the hub which is adapted to admit the square end of the stem14, whereby the valve, disk is 0 rated. This valve disk 12, is alsoprovide with a pair of diametrically opposite openings 15, of the sameform and size as the openings 6 and 32, in the partition 5 and the disk11, respectivel', which, by turning the plate 12, may be mu e toregister with the latter mentioned openings to afford passage of fluidthrough the valve, and may also, be moved so that the the disk 12,covers the opensolid portion of ings' 6 and 32, and interruptscommunication ranged that when the valve is c .Jedges the casing so asto move to and from the fvalve, and 1s eld against turnin position. Thering 16, thus bears against 1 Y the under surface w wall means forpositively casing 7, and-there are a by means of a pair of 17 in theperiphery thereof, which en age a pair of ribs 18, on the .inner wall 0t e plurality ofsprings '19, compressed between the under surface of therin 16, alhd the wall of the casing 7, the said ring and wall beingprovided with the projecting pins 20 and 21, respectively, for holdingthe springs in the proper of the valve disk 12, and by reason ofthetension of the springs 19, holds the valve in tight engagement withthe packing ring 11, and insures a tight joint.

The stem 14, as hereinbefore stated, is provided with a square innerend,which engages the square socket in the hub 13, or any other suitableconnection may be made which will insure turning of the valve disk 12,with the stem 14, and will permit relative movement of thefstem 14, toand from 86 through the wall of the valve disk, and this stem 14,.projects the casing at the opposite' sidethereof' from the valve 12, thesaid being provided with an internally threaded"nipple'22, through whichthe stem 14, extends. stem 14, and threaded into the nipple 22, and saidbushing has the inner end thereof I beveled inwardly so as to have awedge-like and draws the annular gagement with a beveled face of theanar flange 24, with which the stem 14, is provided and effect a tightjoint. A lock nut 25, on.the bushing 23, is turned down against theouter end of the nipple 22, to hold the bushin 23, securely in theposition to which it is adjusted.

For holding the annular flange 24, of the stem tight against theinnerend of the bushing 23, without tensionv on the valve .disk '12, theouter end of the stem 14, is

threaded and hasthe nut 26, turned thereon against a packing disk 27,which latter bears against the outer end of thebushing" 23,

flange 24, ofthe stem tight against the inner endv of the bushing 23, toeffect a tight joint. A look nut 28, is threaded'on the stem 14,against-the nut 26, to hold the latter in the. position to which-it isadjusted.

ny convenient means'may be provided at the outer end of the stem 14, forturning inlet opening 8, of

iametrically opposite notches;

There is a bushing 23, on the the stem and valve disk 12, such as thehand wheel'29, which engages the squared outer end of the stem 14, andis held thereon by means of the cap screw 3 f The operation is asfollows:

This valve may the supply of steam, water or other fluid and has theinlet pipe connected with the the valve and the outlet p1pe connectedwith and the pressure of the fluid coiiperates with thesprings 19, tomaintain a pressure on the under surface of the valve disk 12, to holdsame against the thereby insures an engagement, the slicetiveness ofwhich increases with the pressure of the-fluid and insures a tightclosing valve under all conditions. To open the valve it is onlynecessary to turn thestem 14, a quarter turn and the valve may thereforebe opened and closed quickly and at the same time may beeasily regulatedor adjusted. at intermediate points to permit any desired flow of fluidthrough the valve.

will be noted that by reason of the. loose connection of the inner endof the'stem 14, with the valve disk 12, assembling of the valve is notonly facilitated but ad ustment of the stem 14, to secure the desiredengage ment of the bushing 23, with the annular flange 24, of the stemto effect tight joint I is permitted without efl'ecting a strain on thevalve disk 12, which might otherwise prevent improper seating of thevalve.

While I have shown and described my invention in a preferred form, I am'aware that various changes and modifications may be made therein withoutdepartin from the principles of my invention, and do not purposelimiting the patent granted be used for controlling the outlet opening2,-

thereforepacking disk 11, and
